Abstract

A method is provided involving a gas turbine engine system (20). The method includes configuring a plug (32) within a fluid passage (24) in the gas turbine engine system (20), where the plug (32) is between first and second portions (34, 36) of the fluid passage (24). Material (28) is removed from an interior surface (30) of the fluid passage (24) in the first portion (34) of the fluid passage (24) to provide removed material (28), where the plug (32) substantially prevents the removed material (28) from entering the second portion (36) of the fluid passage (24). The removed material (28) is directed out of the fluid passage (24). The plug (32) is removed from the fluid passage (24).
